The partners for life program: a couples approach to cardiac risk reduction

Area of Science:

• Behavioral Science
• Health Psychology
• Clinical Intervention

Background:

• Marriage is linked to lower morbidity and mortality.
• The role of relationships in adopting healthy lifestyle changes requires further understanding.
• Behavioral change interventions often focus on individuals, potentially overlooking relational dynamics.

Purpose of the Study:

• To compare a patient-only approach with a patient and partner approach for behavior change.
• To investigate the impact of a couples-based intervention on exercise, nutrition, and medication adherence.
• To examine how marital satisfaction influences the effectiveness of lifestyle interventions.

Main Methods:

• Ninety-three patients and their partners were randomized into individual or couples treatment conditions.
• The intervention focused on lifestyle factors including exercise, nutrition, and medication adherence.
• Data from 80 couples were analyzed to assess changes in behavior and marital satisfaction.

Main Results:

• Couples treatment significantly increased physical activity and its acceleration over time.
• Patients in the couples condition maintained physical activity gains, unlike those in the individual condition with marital distress.
• Medication adherence decreased in the individual treatment but remained stable in the couples treatment.
• Nutritional outcomes showed no significant condition or time effects.
• Patients with lower baseline marital satisfaction in the individual condition showed deterioration, while those in the couples condition improved.

Conclusions:

• A couples-based approach to behavior change is more effective for improving physical activity and medication adherence than an individual-focused approach.
• Relational dynamics and marital satisfaction significantly moderate the success of lifestyle interventions.
• Interventions that involve partners show promise for enhancing health behaviors and relationship quality.
